Introduction to Ehrhart theory

  I will give definitions and examples of Ehrhart and h- polynomials, talk on their geometric properties, discuss connection with combinatorics and, finally, prove some fundamental theorems (like Stanley’s Nonnegativity and Ehrhart-Macdonald Reciprocity). NB: Notions and facts from Ehrhart theory will be extensively used in many subsequent talks
